[1166]1Introduction
2============
3
4This is GNU Bash, version 5.1. Bash is the GNU Project's Bourne
5Again SHell, a complete implementation of the POSIX shell spec,
6but also with interactive command line editing, job control on
7architectures that support it, csh-like features such as history
8substitution and brace expansion, and a slew of other features.
9For more information on the features of Bash that are new to this
10type of shell, see the file `doc/bashref.texi'. There is also a
11large Unix-style man page. The man page is the definitive description
12of the shell's features.
13
14See the file POSIX for a discussion of how the Bash defaults differ
15from the POSIX spec and a description of the Bash `posix mode'.
16
17There are some user-visible incompatibilities between this version
18of Bash and previous widely-distributed versions, bash-4.4 and
19bash-5.0. For details, see the file COMPAT. The NEWS file tersely
20lists features that are new in this release.
21
22Bash is free software, distributed under the terms of the [GNU] General
23Public License as published by the Free Software Foundation,
24version 3 of the License (or any later version). For more information,
25see the file COPYING.
26
27A number of frequently-asked questions are answered in the file
28`doc/FAQ'.
29
30To compile Bash, type `./configure', then `make'. Bash auto-configures
31the build process, so no further intervention should be necessary. Bash
32builds with `gcc' by default if it is available. If you want to use `cc'
33instead, type
34
35 CC=cc ./configure
36
37if you are using a Bourne-style shell. If you are not, the following
38may work:
39
40 env CC=cc ./configure
41
42Read the file INSTALL in this directory for more information about how
43to customize and control the build process. The file NOTES contains
44platform-specific installation and configuration information.
45
46If you are a csh user and wish to convert your csh aliases to Bash
47aliases, you may wish to use the script `examples/misc/alias-conv.sh'
48as a starting point. The script `examples/misc/cshtobash' is a
49more ambitious script that attempts to do a more complete job.

51Reporting Bugs
52==============
53
54Bug reports for bash should be sent to:
55
56 bug-bash@gnu.org
57
58using the `bashbug' program that is built and installed at the same
59time as bash.
60
61The discussion list `bug-bash@gnu.org' often contains information
62about new ports of Bash, or discussions of new features or behavior
63changes that people would like. This mailing list is also available
64as a usenet newsgroup: gnu.bash.bug.
65
66When you send a bug report, please use the `bashbug' program that is
67built at the same time as bash. If bash fails to build, try building
68bashbug directly with `make bashbug'. If you cannot build `bashbug',
69please send mail to bug-bash@gnu.org with the following information:
70
71 * the version number and release status of Bash (e.g., 2.05a-release)
72 * the machine and OS that it is running on (you may run
73 `bashversion -l' from the bash build directory for this information)
74 * a list of the compilation flags or the contents of `config.h', if
75 appropriate
76 * a description of the bug
77 * a recipe for recreating the bug reliably
78 * a fix for the bug if you have one!
79
80The `bashbug' program includes much of this automatically.
81
82Questions and requests for help with bash and bash programming may be
83sent to the help-bash@gnu.org mailing list.
84
85If you would like to contact the Bash maintainers directly, send mail
86to bash-maintainers@gnu.org.
87
88While the Bash maintainers do not promise to fix all bugs, we would
89like this shell to be the best that we can make it.

91Other Packages
92==============
93
94This distribution includes, in examples/bash-completion, a recent version
95of the `bash-completion' package, which provides programmable completions
96for a number of commands. It's available as a package in many distributions,
97and that is the first place from which to obtain it. If it's not a package
98from your vendor, you may install the included version.
99
100The latest version of bash-completion is always available from
101https://github.com/scop/bash-completion.
102
103Enjoy!
